[one-users] ssh password less login not function

[Amier Anis]

Hi valentin,

Yes, I'm using packaging from opennebula repo and no error during install
either i created the oneadmin first before install or automatic created by
the installer.

yum -y install opennebula-server opennebula-sunstone opennebula-ozones
opennebula-gate opennebula-flow opennebula-node-kvm


I also has remove selinux from the system.

yum -y remove selinux-policy


Yes, I already configure
​
~/.ssh/config

[oneadmin at mnode]$ vi ~/.ssh/config
 Host *
        StrictHostKeyChecking no
        UserKnownHostsFile /dev/null
  ControlMaster auto
ControlPath /tmp/%r@%h:%p

Thanks you.
